Acuity AR100 Compact Triangulation Laser Sensor

Click2Contact

The ultra-compact Acuity AR100 triangulation laser measurement sensor offers ranges from 10 to 500 mm with a single case size. It is also fast, with a maximum sampling rate of 9.4 kHz.

The AR100 has a linearity of ±0.05% of the full measurement range for most models, and comes with a Class 2, eye-safe laser (<1 mW) in either red (660 nm) or blue (405 nm). The AR100’s enclosure has a rating of IP67, so it can withstand dusty environments and occasional splashes.

The AR100 has a standard RS232 or optional RS485 serial interface for communication with a computer or PLC, and also comes with an analog output of 4–20 mA or 0–10 V. The analog output can be programmed to have a custom measurement span, and the minimum and maximum can be set to any points in the laser’s range. This laser triangulation sensor also has a limit output for indicating alarms, which can be useful for triggering an external device when a target reaches a set position. The AR100 also has an external trigger input to take single distance measurements.

The AR100 triangulation laser sensor is suitable for applications with tight size and mass budgets with high performance requirements.
